ELECTRICITY-DISPELLIZPIG DEVICE FOR PAPER-PRINTING APPARATUS.

To all whom it may concern: Be it known that'I, LLOYD D. SHAW,"2L

' citizen of the United States of America, and

resident of Higgins, in the county of Lipscomb and State of Texas, have invented certain new and useful Improvements in Electricity-Dispelling Devices for Paper-Printing Apparatus, of which the following is a specification.

This invention relates to electricity dispelling means associated with printing presses, folding or ruling machines and has for its objectthe provision of novel means wherebyp'aper being operated upon in the above mentioned machines may be moistened to prevent electrification, its splitting or wrinkling during the process of printing, folding or ruling, thereby avoiding loss of the paper under treatment.

A further object of this invention is to provide novel means for conducting the electricity from the paper while in the course of travel from a pile through a machine, the said device also having the function of slightly moistening the sheets of paper during. their travel.

A still further object of this invention is to produce a discharging brush comprising a body of stiffening material with superimposed layers of absorbent material, capable f of delivering water or liquid by capillaryattraction to that portion of t c said brush with which the paper contacts.

With the foregoing and other objects in view, the invention consists in the detailsof construction as well as in the arrangement and combination of parts whereby a device of this character is produced which will prove comparatively inexpensive as well as efiicient and satisfactory in use.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding parts in the several views, and in which Figure 1 illustrates a plan view of a receptacle witha brush projecting therein and extending therefrom;

Fig. 2 illustrates aview in side elevation thereof;

Fig. 3 illustrates an end view;

.Fig. 4 illustrates a conventional showing of a cylinder and feeding table of a printing Specification of Letters Patent.

press with the electricity dispeller embodying the invention applied thereto;

Fig. 5 illustrates an enlarged sectional view of the brush; and

Fig. 6 illustrates a View in elevation showing a modified form of brush.

In these drawings 10 denotes a receptacle intended to contain water or water and glycerin in proper proportions, the said receptacle being supported in an appropriate way onsome part of the frame of a printing press, ruling or folding machine. As'the manner of supporting the receptacle does not constitute a part of the present invention, it is not shown in detail and it is believed unnecessary to an understanding of the invention and manner of applying it. v The receptacle 10 also has a discharging. brush applied to it, the said brush in the present embodiment of the invention comprising a relatively stiff body 11, preferably of wood or metal and-a layer of absorbent fibrous material such as wool, cotton orpaper, although it is believed preferable to employ wool or cotton fibrous material since it will withstand wear ineident to the travel of the paper on its surface.

As shown in the drawing, a ref 'ceptacle may be placed at either side of a cylinder 13 so that paper being fed from theifiible 14 and being carried by the cylinder pass in contact with the ends of the-brushes, the said paper being thereby moistened, and furthermore any electrification of the paper will be corrected as the electricity "will be discharged through the brushes o the receptacle.

'It'has been found in practice that the fibrous material will take up sufiicient of the fluid when in approximately the fielation to the tank or receptacle as illustrated in the drawing.

In the form of invention shown in Fig. 6, the receptacle 15 has a brush 16 similar in all respects to the brush shown in Fig. 5 with the exception that the fibrous material 17 of the brush which corresponds to the fibrous material 12 of the form first de-' carrying such paper through a printing press, folding or ruling machine. By this or layers 12 last mentioned means, it is possible to adaptthe discharging brush to paper Which'is traveling in a horizontal orsliglitly inclined path and the advantages of such provision will, it is thought, be apparent to those skilled in the art.

I claim:

1. In an electricity dispelling devicefor paper treating apparatus, a receptacle for containing the fluid, a discharge brush comprising a body portion of relatively rigid material and an absorbent material thereon, said absorbent material being adapted to carry water by capillary attraction, the said brush being supported on the bottom and the 15 containing fluid, a discharge brush comprising a body portion of relatively rigid material and an absorbent material thereon, said absorbent material being adapted to carry Water by capillary attraction, and a project-- ing dependlng extension of said fibrous nm- 25 terial.
